Pupils from a Welsh high school will get the chance to speak to astronaut Tim Peake via live link on Saturday.
The lucky students from Builth Wells High School will get the chance to ask Tim questions live from aboard the International Space Station at 10.50am.
Earlier this week Tim sent a special message to thank the people of Wales on St. David's Day.
We're all very nervous but also very excited. It's been a massive project for our school and a lot of work to get to this point.
